U.S. Patents Awarded to Inventors in Maryland (Feb. 22)

(Targeted News Service Via Acquire Media NewsEdge) Targeted News Service Targeted News Service ALEXANDRIA, Va., Feb. 22 -- The following federal patents were awarded to inventors in Maryland.

*** University of Maryland, Georgia Tech Research Assigned Patent ALEXANDRIA, Va., Feb. 22 -- The University of Maryland, College Park, Md., and Georgia Tech Research, Atlanta, have been assigned a patent (8,379,485) developed by four co-inventors for "compressive sensing system and method for bearing estimation of sparse sources in the angle domain." The co-inventors are Volkan Cevher, Houston, Ali Cafer Gurbuz, Marietta, Ga., James H. McClellan, Chamblee, Ga., and Ramalingam Chellappa, Potomac, Md.



The abstract of the patent published by the U.S. Patent and Trademark Office states: "Compressive Sensing (CS) is an emerging area which uses a relatively small number of non-traditional samples in the form of randomized projections to reconstruct sparse or compressible signals. Direction-of-arrival (DOA) estimation is performed with an array of sensors using CS. Using random projections of the sensor data, along with a full waveform recording on one reference sensor, a sparse angle space scenario can be reconstructed, giving the number of sources and their DOA's. Signal processing algorithms are also developed and described herein for randomly deployable wireless sensor arrays that are severely constrained in communication bandwidth. There is a focus on the acoustic bearing estimation problem and it is shown that when the target bearings are modeled as a sparse vector in the angle space, functions of the low dimensional random projections of the microphone signals can be used to determine multiple source bearings as a solution of an l]-norm minimization problem." The patent application was filed on Nov. 3, 2008 (12/740,947). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,379,485&OS=8,379,485&RS=8,379,485 Written by Neha Bharti; edited by Jaya Anand.

*** U.S. Navy Assigned Patent ALEXANDRIA, Va., Feb. 22 -- The U.S. Navy has been assigned a patent (8,379,286) developed by four co-inventors for an "integrated angle of arrival sensing and duplex communication with cats-eye multiple quantum well modulating retroreflector." The co-inventors are David J. Klotzkin, Vestal, N.Y., Peter G. Goetz, Springfield, Va., William S. Rabinovich, Silver Spring, Md., Mike S. Ferraro, Columbia, Md..

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A modulating retroreflector system includes a modulating retroreflector having a plurality of multiple quantum well modulator pixels and at least one transimpedance amplifier. The transimpedance amplifier receives a photocurrent generated by at least one of the plurality of modulator pixels. Each pixel is capacitively coupled to a current driver, which applies a high frequency digital electrical signal to the pixel when the voltage at the output of the transimpedance amplifier exceeds a threshold value. The modulated output of the retroreflector is reflected toward the source of the received optical beam. The system activates high frequency current drivers for only the illuminated pixels, eliminating the need for a separate angle of incidence sensor and reducing power requirements. A low frequency FSK signal can be superimposed on the DC optical interrogation beam and recovered as the unfiltered output of the transimpedance amplifier, to provide simultaneous bidirectional communication without a half-duplex communication protocol." The patent application was filed on May 26, 2011 (13/116,430).
